Suggested Answer: D

Cloud Workstations provides a secure way to preview web applications using built-in preview links, which expose internal ports only via authenticated and authorized access --- no public IP exposure required.

''To preview your app, click the preview icon in the Code OSS panel, which securely tunnels the service to your browser.''

--- Cloud Workstations - Previewing your app

This adheres to Google's security best practices by avoiding public IPs or manual tunneling while enabling developer efficiency.
